car runs fine on highway. In town I can feel like a shuttering and some times it will down shift harder than normal. about a week ago, drove about one mile, stopped for 2 minutes took off again and tran program pop up and car went into limp mode. turned car off and has not happened again. Hope you can shed some light, hooping for maybe a program update.
